Endogeans

Endogeans are a group of organisms that live in the soil. This term is often used in the context of soil biology and ecology, referring to fauna that spends its entire life cycle within the soil matrix. Endogeans include a diverse range of invertebrates such as earthworms, springtails, mites, and various insect larvae. Their presence and activity are crucial for soil health, contributing to processes like decomposition, nutrient cycling, and soil structure formation.

These organisms inhabit different soil layers depending on their specific needs for moisture, food, and shelter. For example, earthworms typically reside in deeper soil horizons where organic matter is abundant and moisture levels are stable. In contrast, some mites and springtails may be found in the upper layers of the soil, feeding on fungi and decaying plant material. The abundance and diversity of endogean communities are often used as indicators of soil quality and ecosystem health. Factors like soil type, temperature, moisture, and the availability of organic matter influence the distribution and abundance of endogean species. Their burrowing and feeding activities play a vital role in aerating the soil, improving water infiltration, and making nutrients available for plant uptake.
